You can choose your preferred audio track using the Properties dialog. See http://forum.conceiva.com/showthread...age-in-a-video. In the current version of Mezzmo (v4.1.3.0), there is no way to set the default audio language for all videos. We're planning to have this in an upcoming version.

If you have an Android smartphone or tablet, then we recommend you install our Mezzmo (Android) app (get it from Google Play store). It lets you connect to your Mezzmo library, browse your folders and playlists, view full metadata & artwork for your files, and push selected files to your devices on your home network for immediate playback. You get full playback controls - Play, Stop, Pause, Seek, Next File, Previous File, Shuffle, Repeat, Volume Up/Down, Mute, etc. In addition, it lets you select the audio track (and subtitle track) for the videos whilst browsing and playing - which is a little more convenient than having to go back to your PC to set the preferred audio track on the Properties dialog.
